I got 47 because...

Tn = Tn-1 + 3×2^(n -1)

Using the above formula,

T2 = 2 + 3×2^(1-1) = 2 + 3×2^0 = 2 + 3 = 5

T3 = 5+ 3×2^(2-1) = 5 + 6 = 11

T4 = 11 + 3×2^(3-1) = 11 + 12 = 23

T5 = 23 + 3×2^(4-1) = 23 + 24 = 47

2(x+3)^2+2(y)^2=32 what is the center point of the circle and how long is the radius
spayn [35]

Answer:

  • center (-3, 0)
  • radius 4

Step-by-step explanation:

The standard form equation of a circle is ...

  (x -h)^2 +(y -k)^2 = r^2 . . . . . . . . . center at (h, k), radius r

Divide your given equation by 2 to put it into standard form:

  (x +3)^2 +y^2 = 16

Comparing to the above, we see ...

  • h = -3
  • k = 0
  • r = √16 = 4

The center point of the circle is (-3, 0); the radius is 4 units long.
